About this tag
The 64-bit port tag covers discussions about porting legacy Windows applications to 64-bit architectures, with a focus on the Space Cadet Pinball frame-rate issue. The thread details how Dave Plummer's original 32-bit port of 3D Pinball for Windows drew frames without a limit, causing excessive CPU usage on modern hardware. Raymond Chen's fix—a simple frame-rate limiter—resolved the problem. This tag is relevant for developers and enthusiasts interested in Windows engineering history, software porting challenges, and performance optimization across different system architectures.

    Space Cadet Pinball: 5,000 FPS, the Frame-Rate Fix, and Windows Engineering

    Dave Plummer’s confession that his port of 3D Pinball for Windows — the Space Cadet table so many of us grew up with — once drew frames “as fast as it could” and reportedly hit roughly 5,000 FPS on newer hardware has resurfaced a powerful, funny and instructive moment in Windows engineering...
